These gases flowing through the turbine housing (2) act on the turbine wheel causing shaft (1) to turn. Compressor wheel (5) sucks in filtered air and -UN-23MAY95 discharges the compressed air into the intake manifold where it is then delivered to engine cylinders. Engine oil under pressure from the engine lubrication system is forced through passages in center housing (4) L30869 to the bearings. 1—Shaft 4—Center housing 2—Turbine housing 5—Compressor wheel 3—Turbine wheel 6—Compressor housing CD,3274,G215,2 -19-16MAY92 215 1
